Hi! Firstly I would like to apologize that my first thread/post is a technical problem rather than a formal introduction, but I would really appreciate help ASAP. The title explains it exactly how it is, with or without a cartridge or keyboard, an Atari XE I recently purchased is presenting me with a constant screen of either dark red or light green. It is important to note that on a separate channel I am continuing to receive a subtle signal of a few unchanging vertical streaks that have occasionally been accompanied by some colour and white noise. This is also unchanging and isn't being received nearly as well as the solid screen. I found a thread discussing this issue on another site, but it was never updated as to whether or not it was resolved. If there are any questions surrounding it that I have forgotten to answer, please let me know! I will be checking this as often as I can. Thank you!
